Bioenno Power BSP-28 Foldable Solar Panels are monocrystalline panels based on high-strength PET polymer laminated solar panels integrated into a rugged polyester canvas (also known as a PVC fabric). The BSP-28 features an extremely portable, lightweight compact structure that provides durability with excellent wear and weather resistance suitable for field use.

The built-in 5 VDC USB output is handy for charging personal electronic devices such as phones and tablets. The 2.1mm DC output jack can be used to charge other devices ranging from 10-15 VDC but can also be daisy-chained together with another BSP-28 for increased output. Designed in conjunction with the BPP-160 Powerpack, the BSP-28 boasts high efficiency and usability and has seen use in many sectors ranging from Amateur Radio to communications and surveillance. Due to its small, folded footprint (the size of the standard laptop), it’s ideal for use on the go.

Note: Bioenno Power Solar Panels DO NOT include a Solar Charge Controller - Solar Charge Controller is sold separately. Always use a Solar Panel with a matching Solar Charge Controller when using a battery – attaching a panel directly to a battery is not advised. Only Cellphones, Tablets, and other personal electronic devices charging at 5V can be attached directly to the panel.
